MAX1724EVKIT+

The MAX1724EVKIT+ is MAX1724 evaluation kit. The MAX1724 evaluation kit (EV kit) is a fully assembled and tested surface mount circuit board that contains two separate boost switching regulator circuits. The left side circuit contains a MAX1724 with a preset 3.3V output. The right side circuit contains a MAX1722 which has an adjustable output voltage. This circuit's output is set for 3.6V. All devices regulate with input voltages from 0.91V to VOUT, making them ideal for 1- or 2-cell alkaline and NiMH battery applications. The MAX1722/MAX1723/MAX1724 feature synchronous rectification and ultra-low (1.5µA typ) quiescent current for maximum efficiency and long battery life. It is used in digital still cameras, low power handheld instruments, MP3 players, pagers, PDAs, personal medical devices, remote controls, remote wireless transmitters, cell battery powered devices.
